We are just about to hit two years since Intel and Micron jointly launched 3D XPoint, and there have certainly been a lot of stories about it since. Intel officially launched the P4800X last week, and this week they are officially launching Optane Memory.

"There's a bit to digest in this chart, but let me walk you through it. The ranges tapering off show the percentage of IOs falling at the various Queue Depths, while the green, red, and orange lines ramping up to higher IOPS (right axis) show relative SSD performance at those same Queue Depths. The key to Optane's performance benefit here is that it can ramp up to full performance at very low QD's, while the other NAND-based parts require significantly higher parallel requests to achieve full rated performance. This is what will ultimately lead to a much snappier responsiveness for, well, just about anything hitting the storage. Fun fact - there is actually a HDD on that chart. It's the yellow line that you might have mistook as the horizontal axis :)."
